Electrician

This course aims at acquainting the Students with the knowledge of both Domestic and Industrial wiring and armature winding of all types of electrical machines such as all types of A.C. & D.C. fan, Motor (Single & Poly Phase) & Generator with the help of thorough classroom theoretical and practical training.

The work of an electrician is versatile, challenging and turns alive the art of creating in one self. They not only have the responsibility to draw electrical layout, design and install, but to see other aspects of the electrical jobs also, like an electrician supervises and controls the usage, purchase and costing, the development and completion of a wiring project.

A trained electrician is also capable of repairing and maintaining different electrical appliances.
